i disagree with you on 1 thing there...

stock kernel even at 1 ghz eats up battery faster than etana at 1.4 ghz
[LG Optimus 2x] tonyp:
of course it has :)
[LG Optimus 2x] skylinegt77:
ty tony :)
[LG Optimus 2x] brudy:
My google play work again. It was only a little server problem.
[LG Optimus 2x] vadonka:
using this two app also highly recommended, since the WIFI also can drain the battery fast:

https://play.google.com/store/apps/details?id=com.lastmile.wifitimeout

https://play.google.com/store/apps/details?id=rubberbibpepper.WiFiTxPower

and remove the DeskClock.apk from the /system/app

its a buggy thing, most of the time prevent the phone from proper sleep.

use the alarm clock extreme app, instead of this.
[LG Optimus 2x] vadonka:
then what is the problem? :)

i work hard on this kernel, and i do this for free, spending my free time for this.

im not Linus Torvalds, so please be a bit more patient.
[LG Optimus 2x] skylinegt77:
this is only for people who have wi fi always on, right?
[LG Optimus 2x] vadonka:
who not use the all the time also can use this two app. only activated when the wifi is turned on.
[LG Optimus 2x] tonyp:
You don't have to hit the thanks button and post in the thread. The first action is sufficient ;)

I think you understood him wrong, he was complimenting you that your kernel is way better than stock :)
[LG Optimus 2x] skylinegt77:
is there aything like that but for 3g?
[LG Optimus 2x] tonyp:
The problem here is that if you'd decrease the 3G chips energy it will use more battery, because a low receiption drains more battery than a strong one.

But I love the Toggle 2G/3G app:

and OMFG PETER!!! XD that post meant like... let me try to explain, stock kernel (1.0ghz)= less performance and battery life than etana (1.4ghz) i meant if we consider this your work is amazing, so why would you be mad at me? :) im a good boy XD

im using the 64 mb ram hack, so aparently i get 435 mb ram, what if i set the compcache to use those 435 mb completely? and, the more times it cleans it the more battery it consumes, right?
[LG Optimus 2x] ykin:
Hi Vadonka.

I've been using your kernel for a few months and I really appreciate your effort to make the kernel with variety features and improve it instantly.

I am using 1205121228-ETaNa_OC_DS_OTF-3.0.y (48MB ramhack) + WIUI 2.4.20 Stable (GB) + V20c CIS.

The kernel is fast and quite stable. The battery life is pleasant (>1.5 days standby) with 2G/wifi connection.

I face three problems with this kernel so far.

1) Easily BSOD while charging over-night and wifi on (screen off freq, 216-324, no BSOD with 2G)

2) The wifi cannot be switched on (error or freezed) after the phone running for some time

3) kworker drained the battery and made the phone hot (not often)

I've tried to update the kernel to newer version since 2012.05.15.

Unfortunately, when I swiped the screen, it responded with 1s delay, although response with tapping is fast. I have also switched off all features in tweakaio.conf which didn't help.

I like this kernel and hope it progress.
[LG Optimus 2x] :
mmmm, this is what you get from flashing while tying your shoe laces, I guess... Flashed ICS Gapps coming back from Owain to Temasek :p

Oh well, it was time for the new beta kernel anyway...

Thanks for the help anyway, everything running smooth again!
[LG Optimus 2x] :
By now, Linus could probably learn a thing or two from you...

[LG Optimus 2x] skylinegt77:
u can get it from vadonkas share thingy, right there at the op
[LG Optimus 2x] emmanuelcassar:
will there be any stable versions? or everything beta?
[LG Optimus 2x] spica1234:
Reffer 1st post or 3rd:)
[LG Optimus 2x] skylinegt77:
ok, i just noticed, on my phone the etana config app wasnt doing a thing, i went and edit the tweakaio myself coz the app seems it wasnt saving the modifications
[LG Optimus 2x] skylinegt77:
i also noticed something else while running antutu benchmark, and i was like WTF???

id love it if any1 could explain whats wrong with the emmc memory to me XD
[LG Optimus 2x] lineagesum:
Laggy after watched a video on 0521 kernel
[LG Optimus 2x] vadonka:
im updated the developement status in the OP. currently im on a battery life test run, but the new kernel is compiled succesfully. soon as my battery is drained i will test the new version.

battery run status: powersave version 216-1408Mhz, highly undervolted. im on battery only for 2 days 16 hour now and im still have 30% battery level. im using my phone like always. i try to reach the 3 day treshold :)

ooh i almost forgot: i will build a shared, -32m, -64m ramhack version with the normal and the powersave version.
[LG Optimus 2x] ron_gangte:
Waiting for it. :-D
[LG Optimus 2x] 12rithy:
Thank you very much! Hope we can get USB OTG in our O2X
[LG Optimus 2x] miina_tokiha:
now this is good news for me.

I'll help testing it.
[LG Optimus 2x] vadonka:
i cant test this because im not have any device/cable what can be attached to my o2x, but i build a test version with OTG implement if you want.

i think its better that not included to the main kernel... its a beta not tested patch.
[LG Optimus 2x] CVonV:
i'm trying to see the longest mine will last too.. i turned off my LED notifications and hardly touch the phone.. i'm on 11hrs and 40m with 40% left atm (48% cell standby, 46% phone idle, 6% display, 2% voice calls).. so if i reach 20 hours on a single charge.. i'd be pretty content with that

just wondering.. how do you UV?
[LG Optimus 2x] vadonka:
im working on updating my compiler script, that can handle some parameters, with this i can build every version what i want just pushing the enter button once :) its helping me a lot because im too lazy sometimes :D
[LG Optimus 2x] sunstorm:
Dear Vadonka,

I thought the shared memory versions were giving problems? Did you manage to overcome the issues?
[LG Optimus 2x] vadonka:
the shared memory version patch is not my idea, i just appyled it. sadly im not have that much programming skill in C language to investigate the problem.
[LG Optimus 2x] ron_gangte:
It worked fine for some people including me. So please build a shared memory version too.

Thank You. :-)
[LG Optimus 2x] rQvsnaps:
Ahoy

Tried installing the normal version today, for some reason I can't get past the LG screen when I reboot ? My phone just hangs there, and gets really hot just above the battery on the back? If I reboot a second time it just hangs on a black screen with notification lights on.

Running temaseks kang

Any ideas ? :-) thanks
[LG Optimus 2x] drpele:
I try to flash vadonka's latest kernel on MIUI.hu 2.1.6 and 2.1.13 but the installer says "Current ROM is not compatible with LGE kernel! Aborting..."

What could be the problem with the attached buld.prop?
[LG Optimus 2x] Supupa:
Oh really? Though when i flash, kt gives me a black screen after after lg logo at boot ):
[LG Optimus 2x] CVonV:
21hr 47min with 1hr 9min on display and 4min on voice calls.. no texting.. little facebook.. no web browsing.. no gaming.. no music.. no video.. some xda foruming.. and 3 pictures taken on camera.. LED notifications off and auto brightness

this is my third cycle (2nd cycle was 9hr 8m with plenty of usage though)
[LG Optimus 2x] laichung:
Please build a test version, I have the OTG cable and I can test it. Great thanks
[LG Optimus 2x] koboltzz:
You can easily expand your battery uptime if you kill apps by holding your 'back' key (enable this in settings->apps->developement->kill apps).

There are many apps, that seem to use gyroscope even when screen off. Check that in 'spare parts' sensor usage.

These apps (like camera apps) will drain your battery very fast, if not killed.
[LG Optimus 2x] vadonka:
here is the battery run test result:

using powersave version (cpu max 1408mhz) with heavy undervolt, wifi disabled when screen is off, tx power lowered to 11dBm, 2g always enabled, cpu speed limited to max 816Mhz when battery level is lower than 20%, never use airplane mode. using the stock LGE battery.

phone using for normal phone calls, sms, gaming and browsing some times. this is a normal usage, of course with heavy usage the battery will discharge faster.

(this is my personal record. i cant reach 3 day running time from battery for now)
[LG Optimus 2x] snoopy11hk:
Hello, i just flash your kernel but weird things come, the /sdcard can't mount, wifi isn't working, what can i do now??

thank you for your help:D
[LG Optimus 2x] CVonV:
I do have that enabled.. and i usually kill apps that way

and yeah i checked spare parts for the sensor usage and it was hardly ever used during the 21hrs

how do you get the cpu to max at 816 when battery is 20%? and also the tx power.. and the undervolting.. or are all these settings just built into the power save kernel?

gosh i'm jealous of your battery time!

ps what theme are you using for your status bar?
[LG Optimus 2x] snoopy11hk:
Hello, i just flash your rom+kernel but weird things come, the /sdcard can't mount, wifi isn't working, display light can't be controlled what can i do now??

thank you for your help:D
[LG Optimus 2x] powwow88:
I've made a test too and I got 150 for sd card write and it's 15,9 MB/s, so your point is correct. Propably nothing wrong with your card, just an antutu bug. Test it again.
[LG Optimus 2x] skylinegt77:
the part that bothered me wasnt that, it was actualy the reading speed part XD

but thanks

---------- Post added at 06:24 PM ---------- Previous post was at 06:18 PM ----------

ive done about 20+ tests till now and all of them give me a very high writing speed and a very very low reading speed
[LG Optimus 2x] powwow88:
Oh, I see... Maybe the changes what you've made in tweakaio config file are causing this.
[LG Optimus 2x] skylinegt77:
i doubt that because its a tweakaio that i saved on my sd card so i wouldnt have to change it everytime i reflash a new version of the kernel, but hasnt given me this prob till now
[LG Optimus 2x] kickokim:
Same here...
[LG Optimus 2x] Shadowchaz:
Hi as a test I have installed temasek voodoo kernal and my skipping music has now gone.

When I run the latest beta I am getting really bad skipping sound.

I have tried changing schedulers but nothing seems to help. I wondered if it could be linked to the problem of slow read write on SD card some of us seem to be having?
[LG Optimus 2x] vadonka:
slow sd: test your sd card woth 'sd tools' if only the usb transfer speed slow but the internal io speed is fast then its not causing lag in the system

lag after video play: try mx video player with arm v7 codec pack. i have a feeling that issue is related to the cm7.
[LG Optimus 2x] skylinegt77:
maybe. or maybe its just related to your screen off max freq...
[LG Optimus 2x] kickokim:
Mx player works, but I don't have this issue with other kernels, not even the stable etana. Only with last betas.
[LG Optimus 2x] kickokim:
And by the way, exept for video issue and a little screen off drain this last beta seems super smooth and quite stable!
[LG Optimus 2x] Shadowchaz:
I don't think so. I set vandonka kernal to 312mhz min and it still skips.

Cm7 temasek kernal is set to 256 MHz and no skipping.

One thing it seemed to happen if the phine was rotated even if screen was off. Could it be something like its still rotating the screen, even though screen is off? Does the kernal control this?
[LG Optimus 2x] yarisd4dturbo:
With miui it's all ok on latest beta ;)...thx Vadonka!!!
[LG Optimus 2x] vadonka:
thx for the report. i will investigate the difference between the last beta and stable.
[LG Optimus 2x] TrymHansen:
Myrt OTF updated to 0.7.0. Adds support for EtaNa's enhanced OTF.
[LG Optimus 2x] kickokim:
Can't find it, do you have a link?
[LG Optimus 2x] vadonka:
working great!

can you integrate a switch for the nitro feature? :)
[LG Optimus 2x] vadonka:
beta kernel is updated, details in the op.

the most important thing, all wifi issues are solved. wifi reconnection should super fast as like in the 2.6.32 kernel.
[LG Optimus 2x] TrymHansen:
Maybe. I've completely redesigned the internals, so adding a setting is very quickly done now. I need to do some testing first though, I don't add settings just cause they're there, they actually need to make a measurable difference. Will test that and the other parameters when I get the time, no promises.
[LG Optimus 2x] ykin:
Hi Vadonka

I'm so happy to see your update. Thanks for your work.

although swiping is still laggy with 1205220054-ETaNa_OC_DS-3.0.y :o

I have removed DeskClock.apk and been still observing if my phone'd get better.

On the other hand, your phone's standby time is awesome. Do you use any power saving app?
[LG Optimus 2x] alakyr:
just installed and the first impression it's ever more smooth and wifi reconnection is very fast!!!

again an awesome work vadonka!!! (LG should take you to mantein his kernels =P)
[LG Optimus 2x] antec123:
have you assign KSM value to no?? there is in first page of the OP. i know this is related to after users use the heavy apps but it's worth to try
[LG Optimus 2x] ykin:
Except Script Enabled, I set them all off. :rolleyes:

Thanks.
[LG Optimus 2x] reginickneo:
You can find it in the app section. :)

Everything's ok with the latest kernel. Ty. :R
[LG Optimus 2x] powwow88:
Vadonka you're a f*****g wizard!:D The huge wifi drain is really fixed.:) Thanks!
[LG Optimus 2x] alakyr:
harry potter? xDDDD
[LG Optimus 2x] brudy:
Newest today kernel, KSM disabled, but after play video the problem is the same.

Everything else works perfectly.
[LG Optimus 2x] fuxmen:
How about Setcpu?
[LG Optimus 2x] kickokim:
Same here, still have the video issue.:(
[LG Optimus 2x] vadonka:
who have the laggy video play issue please try one of these versions:

http://etana.donka.hu/kernel/?dir=3.0.y/test
[LG Optimus 2x] kickokim:
Same problem! :banghead:
[LG Optimus 2x] vadonka:
there is only one thing left what can caused this, but if i revert that the game compatibility issues happening again (plants vs zombies, draw something, etc)
[LG Optimus 2x] vadonka:
one more thing, do you use ramhack?
[LG Optimus 2x] powwow88:
I've just tested and I have that swipe lagg after playing a video in cm7 player, but I'm not using this player anyway so it's not a problem for me...

I use MX Player when I need crop function and in any other case I use MoboPlayer cuz it eats half as much battery than MX Player and some other player what I've already tried.

I'm using 32MB ram hack.
[LG Optimus 2x] kickokim:
No, i never activate rh... with last test there's bad screen off drain, is it a normal conseguence of something you have reverted? I don't mind loosing those games since I don't use them!
[LG Optimus 2x] vadonka:
yes, im only deactivated one feature in the kernel config, but this is actually help to save battery. it was just a test, but not this caused the video lag.
[LG Optimus 2x] vadonka:
so the issue is only happening with the stock cm7 video player, but the third party apps are fine?

im using mx video player too and i never had this issuse.
[LG Optimus 2x] silentmelodies:
Vadonka, after flashing the 21 May beta, I get massive touch input lag. I don't know what's wrong, but strangely the phone itself doesn't lag. Animations and even videos still play smoothly. There seem to be a problem in communicating the input from the touch screen to the OS itself. I can be sure this is caused by the latest beta, because I've reproduced this two times.

Reflashing the ROM does solve the problem, but reflashing another kernel only does not.
[LG Optimus 2x] powwow88:
Yes, it seems. Btw., If I do a simple lock-unlock then the lagg is gone

[LG Optimus 2x] kickokim:
Yes, mx player is fine, I also use it, only standard video player has issue. It's a strange issue! It might brake other things aswell, but I only know about video player right now...
[LG Optimus 2x] brudy:
Are you tried the 22 May beta?
[LG Optimus 2x] vadonka:
it is possible that the nvrm_daemon causes the issues after all

im currently tested this.
[LG Optimus 2x] silentmelodies:
I have. It happens with both 21 and 22 beta.
[LG Optimus 2x] alakyr:
with the beta22i just had a self restart while sending a sms...and before i had a freeze while the screen was off and had to remove the battery cause it was stuck...
[LG Optimus 2x] mind_challenge:
I have no such problems at all. Tried 1080p with MXplayer and still no lag.
[LG Optimus 2x] thewoZa:
Only happens with stock player - I can confirm this on latest WIUI too. Fine with MX Player but not with stock. Reboot needed to get working properly again.

Thanks
[LG Optimus 2x] fuxmen:
22nd version, 1.5h and only 1%drop :D wifi, data, 216-1200mhz light use, This ROCKS!!
[LG Optimus 2x] antec123:
sorry m8 i use mx video player and no have a lag issues, sorry can't help. i think you should wait for vadonka to solve the problem since he is our wizard :D
[LG Optimus 2x] vadonka:
i found the rare touch screen lag issue.

and i found the problem of the video play lag, but i dont know what can i do for now. the problem is that the hdmi port is activated and remain active until a screen off/on. thats why the screen power off solved the issue.

just i dont know why this is happening :)
[LG Optimus 2x] kickokim:
It's definitely in something you added after last stable relese, also the beta right after (6 may) didn't have the problem. After that I always had the issue.
[LG Optimus 2x] vadonka:
There is only one kernel config option what can be caused this

the SWP_EMULATE

currently this is disabled, but if i enable back some games will not work.
[LG Optimus 2x] silentmelodies:
I'm honestly very impressed with how fast you manage to find the cause of these bugs.

Thanks alot for your hard work :)
[LG Optimus 2x] vadonka:
re-enable the swp emulate option solve the lag after video play issue, but broke the compatibility for the plants vs zombies, draw something, etc...

so its a dead end
[LG Optimus 2x] skylinegt77:
funny thing is i never had that kinda issue after watching a video with the same kernel
[LG Optimus 2x] vkk178:
May be you can give some sort of option to change this setting at runtime .. until a more permanent solution is found
[LG Optimus 2x] vadonka:
use any other (free) video player and problem is gone. it seems the issue only occured with the stock cm7 'music.apk'

by the way this app is missing from the cm9. what is replaced this?

swp emulate is not such a thing what can be enable/disable at runtime :)
[LG Optimus 2x] skylinegt77:
if you mean the musik apk, its was substituted by apollo apk
[LG Optimus 2x] fuxmen:
it's not worth a strugle IMO, MX player beats the hell out stock ;D
[LG Optimus 2x] hadi_rena:
Hmm so the choice is laggy after watch some videos or unable to play some game :confused:

If possible that we can change that value using OTF will be AWESOME :D but if I would choose fix video thing instead of game.

@vadonka: you're the dev so and we are the user :D or you can ask public opinion which one to be fixed. VOTE for video fix
[LG Optimus 2x] vadonka:
are you serious? :)

just use the mx video player

its free, and much more advanced and faster than any other stock player.

and doesn't have this lag issue.

i think most of the users prefer the game compatibility.

like i said swp emulate cant be control via the otf.
[LG Optimus 2x] skylinegt77:
i think u guys are missing the point here... his kernel is perfect... all u have to do is download mx video player...
[LG Optimus 2x] fuxmen:
I have problem playing music with player pro on headphones with beta 22 21 play for about five minutes then stops and bsod :(canYou master look at this?

[LG Optimus 2x] skylinegt77:
just an idea, but u could jam mx player together with ur otf app in the kernel pack ;)
[LG Optimus 2x] koboltzz:
Hey vadonka,

after some tests, ext3 seems to be more batteryfriendly than ext4 (on all 3 partitions).

I know ext4 is faster and evolutionary, but test it yourself ;)

What about a switch in etana.conf for chosing ext3 or ext4?
[LG Optimus 2x] hyyuga:
Unfortunately i experienced 3 bsod with the latest beta and #107, 2 after a call and one after receiving a message, but i also disabled ksm, so this could be the problem tooand my battery drains really fast..itseems i have to full wipe again :-( otherwise it is so fast, i love it. Hopefully i can solve those issues..
[LG Optimus 2x] kickokim:
As long as the problem is just lag after stock video, it doesn't really matter. I always use mx player anyways! Thanks for your work!

At least now we know what the problem is and you can write it in op.
[LG Optimus 2x] CVonV:
oh i didn't know draw something was compatible now! thanks vadonka! that was the only reason why i reverted to stock temasek kernel ><

also, i think you need to edit your default voltages on the 2nd post as it doesn't correspond to the default readings in setcpu

i agree with u that ext3 saves more battery than ext4, but if you compare performance wise, ext3 has such a decrease in performance that it doesnt compensate for the extra battery life. just my opinnion tho :)

[LG Optimus 2x] brudy:
I have a bad news guys. Because Vadonka's advice I changed the stock alarm clock to alarm clock plus. When I exit from alarm clock plus, I have the same problem with stock video player. This problem is maybe bigger then we have thinked earlier.

Please somebody try this.
[LG Optimus 2x] powwow88:
same here
[LG Optimus 2x] hadi_rena:
:D you're right most people choose game... than it's not a problem ? I already use MX Player and don't have problem at all.

So my guessing are wrong :p. Ok you're the dev and know better than us
[LG Optimus 2x] Najmuddin NP:
The lag thing is not limited to stock video player . I use touch key lights app to turn off the led lights, everything was fine until the latest kernel. Since then whenever I reduce the led brightness to 0 the phone becomes unusable until I increase the brightness. So I have stopped using it now.
[LG Optimus 2x] vadonka:
Thx for the report. I guess i know whats behind this. Im not near pc now but i will check this out later.
[LG Optimus 2x] vadonka:
One more thing. After the video play the touch keys are off, but if you enable it back from the lg notifications app, the lag is gone. The screen off/on also reenable the touch keys, thats why solved the issue. So the problem is not the video play app but the touch keys.

If the touch keys are off the touch screen will inresponsive but the phone not only the touch screen.

This info will help me a lot for a quick fix. It seems this is the only major issue what remain.

I will investigate this later
